I think that what gives TOS design its ongoing plausibility is its purposeful vagueness. There are no explanatory instructions on the communicator, phaser or tricorder. The consoles are very vague about what they do. We could go back and show someone on the TOS bridge bringing up a holographic display and it would make plenty of sense because there is enough room there to speculate about other purposes.

The painstaking detail taken in designing a set like the NX-01 bridge ends up being self defeating as the years roll by and all those things it says it does become more and more laughable as being things that would be done another way.
